| Subject: | two modules which export conflicting methods produce warnings |
The current behavior is to never unload a module from memory, so if you
test two modules with conflicting exports, you can warnings. The
warnings can make it appear that there is a problem, when there is not.
This example illustrates the issue, but requires a bit of modification
to point to where CGI.pm and CGI::Carp are installed on your system:
use lib 'perllib';
use Test::Compile 'no_plan';
BEGIN {
pm_file_ok('perl5/perlbrew/build/perl-5.14.2/lib/Carp.pm');
pm_file_ok('perllib/CGI/Carp.pm');
}
Running that produces the following output:
